The American Civil Liberties Union has filed a motion for preliminary injunction to require Michigan to recognize the marriages of hundreds of same-sex couples who were married in the state in March.

Approximately 300 couples were legally married before the Sixth Circuit Court of Appeals put on hold U.S. District Court Judge Bernard Friedman's decision that struck down Michigan’s ban on same-sex marriage.

A few days later, Governor Rick Snyder announced that, while the 300 marriages were legal, the state would not recognize them for the purposes of providing state benefits that are afforded to married couples.

ACLU attorney Jay Kaplan says the state cannot strip a married couple of recognition after it issues a valid marriage license.

The ACLU filed a lawsuit in April arguing that the state had violated due process and equal protection rights by refusing to recognize the marriages.

Snyder says state recognition should wait until the appeals end. The federal government is recognizing the marriages.
